gage. Fig. 2 shows the gage-bar cut perpendicularly through the center.

In these drawings, A is the gage-block, ar-

. ranged to traverse on the gage-bar B, and mayv be fastened in the position desired by the setscrew C. The bar B has a groove, D, in its under side, except a short piece, E, at the lefthand end, in which a pivot is fixed, projecting into the groove, for the marking wheel F to turn on as the gage is traversed. There is a slot, G, in the bar B, and slotted metal plates H H are fastened in the bottoni of the groove and on the top of the bar, to form seats for the traversing block I and its nut J, which turns on the screw-stem K of the block I, to hold it when adjusted. There are two prongs projecting from the block I to support the pin on which the marking-wheel L turns when used.

The marking-wheelsF and L are made,in' the form shown in the drawings, With a thin edge to cut or make the mark and a hub to roll on the material marked as the gage is traversed.

There is aqpiece of metal, M, fastened in the side of the-gage-block A to hold the pivot of the friction-roller N, which turns in the groove D and rolls on the material gaged.

In using this gage to make two marks, ad-

just the marking-wheel L a proper distance Figure lis a plan of the under side of thefroin the wheel F, and then adj ust the block A al proper distance from the wheel L. It only 'one mark is required, remove the block I and cutter L from the bar B. l

What I claim as my improvementin carpenters gages is- Arranging the adj ustablc standl which carries the markingwheel L to traverse in the slot G of the gage-bar B, substantially as described.
